Forms

invāsiō f (genitive invāsiōnis); third declension[1]

Etymology

It is from Latin invādō (“to enter, attack”) + -tiō, a noun of action from the verb.[2][1][3]

Earliest recorded meaning

The TLL finds no example before the 4th century.[2] Köbler's first source is Ambrose, where it means an attack.[4]

Semantic evolution

Late Latin used it for a hostile attack or invasion, where earlier writers had said incursio or aggressio;[3] Symmachus has it in his letters,[3] and Tiberius Claudius Donatus speaks of defending a city against the invasion of the Trojans.[2]

In medieval Latin it also meant violence in general and, in law, the usurpation or unlawful seizure of property.[5] The early medieval law codes use it,[4] and in English law invasio domus was house-breaking, an assault on someone in their own home.[6] English took invasion from it through Old French in the 15th century.[7]

Timeline

  • c. 340–397 AD – Ambrose uses it for an attack.[4]
  • c. 340–402 AD – Symmachus uses it in a letter.[3][4]
  • mid-15th century – English borrows invasion through Old French.[7]
